MACHINE FOR MANUFACTURING CYLINDRICAL RODS.

SPECIFICATION forming part of Letters Patent No. 404,654, dated June 4, 1889. Application filed October 1, 18 88. Serial No. 286,880}. (No model.)

To all whom it may concern:

Be it known that I, HENRY I-I. Posr, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Machines for Manufacturing Cylindrical Rods, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. I

Thepurpose of this invention is to manufacture curtain-rollers and analogous cylindrical wooden rods from square or angular bars in an expeditious and perfect manner with a minimum expenditure for manual labor; and to that end the invention consists in the novel construction and combination of the components of the machine, hereinafter fully described, and specifically set forth inthe claims.

In the annexed drawings, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical longitudinal section of said machine; and Figs. 4, 5, 6, and 7 are vertical transverse sections, respectively, on lines 00 w, y 1 z z, and O 0 in Fig. 2.

Similar letters of reference indicate corresponding parts.

A represents the supporting frame or bed of the machine. On the said bed are rigidly mounted the pedestals B 13, having journalboxes 0 c axially in line with each other. In said box is mounted the hollow shaft a, the interior of which is of a sufficient diameter to receive longitudinally through it the wooden bar to be operated on. This shaft receives rotary motion by a driving-belt running on a pulley D, secured to the said shaft between the pedestals B B. To opposite ends of the shaft a are rigidly secured cutter-heads b b, of different gages or diameters, and disposed axially in line with each other and with the shaft.

The cutter-head b is of a greater diameter than the cutter-head b, and in front of the former and in range therewith are feed-rolls R R, formed with V-shaped circumferential guide-grooves d, and pivoted to pedestals which are rigidly mounted on the bed A. A similar pedestal B is secured to the bed a short distance from the opposite end of the bed A.

shaft a, and on this pedestal are pivoted the guide-rolls R R, having U-shaped circumferential grooves e in range with the axis of the cutter-head b.

P P are two pedestals, also firmly secured to the top of the bed A, and on these pedestals is mounted the finisher, consisting of two spiders or heads I I, which are firmly united by longitudinal bars I I", and have projecting therefrom in opposite directions prolonged hollow journals or shafts i 2', the interiors of which constitute passages extending through the heads I I and arranged axially in line with each other. The journal-box p of the pedestal P has either rigidly attached to it or formed integral with the end adjacent to the head I a gear-wheel Z, and at the opposite endof said journal-box is a drivingpulley F, attached to the journal N N denote abrading-cylinders, preferably faced with sand-paper, which cylinders are firmly secured to shafts m n, journaled in the heads I I, and arranged equidistant from and parallel with the axis of the said heads. To one of the ends of each shaft 71 is fastened a pinion 0, which meshes with the gear-wheel Z. This wheel being stationary while the heads I I are rotated by the pulley F, causes i the pinions 0 0 to revolve and impart corresponding rotary motion to the abrading-cylinders N N.

The feed and guide rolls R R are rotatedv synchronously by means of a counter-shaft D, parallel with the axis of the hollow shaft a, and journaled on brackets ff, secured to the bed A. To this counter-shaft are secured a drivingpulleyH and a bevel-pinion L, which latter meshes with a bevelgear-wheel J, pivoted to a bracket T, secured to the side of the To the hub of this bevel gear-wheel is secured a pinion g, which meshes with a large gear-wheel V, mounted on a bracket U, secured to the bed A. To each set of shafts of the respective feed and guide rolls R R are attached gears h h, which mesh with each other, and gear-wheels t t, pivoted to suitable supports on the bed A, transmit motion from the gear-wheel V to the two sets of gears h h.

In the operation of the described machine the square or angular bar is inserted endwise between the feed-rolls R R, in the direction indicated by arrows in the drawings. Said feed-rolls pass the bar into the cutter-head I), which partly trims off the corners of the bar. From thence the bar passes through the interior of the shaft a and through the cutterhead I), which further reduces the diameter of the bar and imparts a cylindrical form thereto. From thence the bar is conducted by the guide-rolls R R into the adjacent hollow journal 2', and which guides the bar so as to carry it between the abrading and finishing cylinders N N, each finished rod being forced out endwise from the finishing-cylinders and through the second hollow journal 1' by the succeeding bars introduced in the machine.

Having described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the pedestals P P, formed with journal-boxes, hollow shafts i i, mounted in said boxes, heads I I, rigidly attached to said shafts, driving-pulley F, attached to one of said shafts, shafts n n, journaled in said heads, and abrading-eylinders N N, and pinions o 0, attached to the latter shafts, as shown, of the stationary gear-wheel Z, meshing with the said .pinion and rigidly attached to the journal-box of one of the podestals, substantially as described and shown.

2. The improved machine for forming cylindrical rods, consisting of the bed A, pedestals B B 3 3" and P P, mounted on said bed, the hollow shaft a, journaled in the pedestals B B, pulley D, secured to said shaft between the pedestals, cutter-heads b 1), secured to opposite ends of the aforesaid shaft, feed-rollers R R, pivoted to the pedestal B and formed with V-shaped grooves in their peripheries, guide-rollers R R, pivoted to the pedestal B and formed with U-shaped grooves in their peripheries, the heads I I, rigidly united and having hollow journals 1' 2', mounted in the boxes of the pedestals P P, the gear-Wheel Z, fixed to one of said boxes, the shafts n n, journaled in the heads I I, the abrading-cylinders N N, secured to said shafts, pinions 0 0 on the ends of the shafts, meshing with the aforesaid gear-wheel, and the pulley F, attached to one of the journals 7', substantially as described and shown.

In testimonywhereof I have hereunto signed my name, in the presence of two witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 27th day of Septemher, 1888.
